2026-05-02	fix BPF tracepoint context type for RHEL 9 stock kernel	Paul Buetow
	The BPF handler generator emitted struct trace_event_raw_sys_enter/ trace_event_raw_sys_exit (the BTF-blessed aliases). RHEL 9 carries an rt-tree backport that adds preempt_lazy_count to struct trace_entry, which widens those aliases by 8 bytes and shifts args/ret. The actual tracepoint context the kernel hands the program is still syscall_trace_enter / syscall_trace_exit, where the offsets did not move. Programs typed against the wider alias read past max_ctx_offset and the verifier rejects the attach with EACCES. Switching the generator to emit syscall_trace_enter/exit lines up with the real context on RHEL 9 (and is identical on every other distro, since the two structs only diverge there). Same fix bcc shipped in iovisor/bcc#4920 and inspektor-gadget did in inspektor-gadget#2546. Field accesses (ctx->args[N], ctx->ret) are unchanged. Verified end-to-end on Rocky Linux 9.7 stock 5.14.0-611.5.1.el9_7 (no kernel-ml needed) and Fedora 6.19. README rewritten accordingly: drops the elrepo kernel-ml step and the trailing 'permission denied' troubleshooting paragraph; adds a historical note explaining why the old workaround existed.
